MILK AND CREAM SEBARATORFOR BOTTLES.

Specification of Letters Patent.

Patented Apr. 8, 1913.

Application filed September 16, 1910. Serial No. 582,407.

To all whom t may concern Be it known that I, FRANK M. KIGER, a citizenof the United States, and a resident of Gresham, in the county ofMultnomah and State of Oregon, have invented a new and usefulImprovement in Milk and Cream Separators for Bottles, of which thefollowing is a specification.

It is the custom, as well known, at the present time to pour the freshmilk at the dairy into bottles which are afterward sealed and sodelivered to the customers, to assure and guarantee that each customerwill receive the same proportions of milk and cream as contained in t-hemilk in its original state. After the bottle has stood a while the creamwill gather at the top, and frequently the housekeeper finds itconvenient to draw off the cream, for use iny coffee and other specialpurposes, and then use the milk in cooking.

Vith this knowledge in View, my invention has for its object to providean ineX- pensive device by which, under the conditions referred to, t-heheavier milk can be withdrawn from the bottle, so as to leave thelighter cream remaining therein, which may finally be poured intoanother pitcher.

To this end my invention comprises the special arrangement of parts andfeatures hereinafter fully described.

In the accompanying drawings: Figure 1 is a longitudinal section of abottle into which my device is inserted, as in practice; the bottle isrepresented as containing milk which is supposed to have been standingfor a suiiicient time to cause the formation of an upper stratum ofcream; and this view illustrates the operation of my device to pour outthe heavier milk-portion of the liquid, thus separating it from thecream and leaving the latter in the bottle; Fig. 2 is a side elevationof my device, sho-wing the two tubes of my device brought together bythe reiieX action of the shield, 'thereby so arranging the two tubes asto be able to insert them in the neck of a milk bottle; and Fig. 3 is atop view of my device, looking at the shield straightened out, thuscausing the tubes to spread apart, as shown in Fig. 1; this being thenatural arrangement when my device is secured in the neck of a bottle.

My device consists of a circular seal or shield, @which may be made ofany suitable material, preferably {ieXible and resilient, so as to bemore readily seated in the neck, of the bottle c, as shown in Fig. 1.

In the circular shield, a, is secured one end l of a tube Z for pouringout the liquid, and hence preferably of larger diameter, and an airtube, c, of smaller diameter. The

tubes, d, e, are curved, as shown, so as to bring the inner ends thereofagainst the top land bottom sides of the bottle, as shown .in

to permit the tubes, d, e, to be brought together, as illustrated inFig. 2, for insertion in the bottle. Resiliency is, furthermore, aconvenient property of the shield a, to insure that before my device isinserted in the bottle the reflex action of the seal will bring the twotubes together at their bend, as shown in Fig. 2, and thus arrange themfor insertion in the bottle, and when the shield is inserted in thebottle, straightened out, the tubes will be simultaneously spread apart,as shown in Fig. 1. The shield, a, may be made of metal, but when somade, in order to render it liquid-tight, when seated upon the innershoulder f of the milk bottle, I place a disk of any suitable materialunder it.

When using my device, the usual paper seal of the bottle is firstremoved, and then my device is inserted as illustrated in Fig. 1,supposing that the milk has been standing for a suiiicient time toseparate the cream and cause it to float on the milk'in the form of atop stratum, as usual. The bottle is then so manipulated that the tube ddraws out the more limpid, milk portion of the liquid, while t-he cream,represented in Fig. 1 by the heavier and closer broken lines, willremain in the bottle. The device is `then removed and cleaned and putaway for future use. The tubes, (l, e, may be made of any material foundconvenient, and they may be either permanently or removably inserted inthe circular shield a.

Instead of arranging my device as above described, the tubes, d, e, maybe rotatably or adjustably held in the shield a, given a quarter turn tobring them side by side, for insertion in the bottle, and, after havingbeen so inserted, turned back, so as to spread the lower ends of saidtubes apart and against the opposite sides of the bottle, as mentioned.I prefer merely the automatic form, so as to render the use of my deviceconvenient, and to assure that When inserted in the bottle of milk itWill be properly arranged, for operating as described.

I claim:

A milk and cream separator consisting of a Wafer-like disk or shieldmade of resilient material so as to be adapted to be removably sprunginto place in the mouth of a container the neck of which is formed Withan interior circumferential shoulder, a liquid pouring tube secured insaid shield and curved out-Ward, and anv air inlet tube also secured insaid shield and curved in the opposite direction, both of said tubesbeing made of sufficient length so as to extend to- Ward the bottom ofthe container in which they are to be inserted; said shield beingadapted to cause the act of seating said shield on the shoulder in theneck oi' a bottle to spring and hold the inner ends of said tubesagainst the opposite sides of the container, and when the shield isremoved from the neck to cause the shield to automatically so bend as tobring the two tubes together, whereby the insertion of the tubes andtheir removal from the container is facilitated.
